摘要

(5R)-4,5-dihydro-isoxazole derivatives as well as 1-(2-chloroacetyl)-4-piperidinecarbonitrile and 1-(2-chloroacetyl)-N-(1,1-dimethylethyl)-4-piperidinecarboxamide as intermediates in the preparation of e.g. 4-[4-[(5R)-4,5-dihydro-isoxazoI-3-yl]-thiazol-2-yl]-piperidine derivatives as fungicides for crop protection.;Exemplary intermediates are e.g. N,N-dimethyl-[(5R)-4,5-dihydro-5-phenyl-isoxazol-3-yl]-carboxamide and 2-bromo-[(5R)-4,5-dihydro-5-phenyl-isoxazol-3-yl]-ethanone.
